Two ways of lack of basic services major negative impact on the health of poor people in south africa

I inferred your question to be; Two ways in which the lack of basic services causes major/negative impacts on the health of poor people in South Africa.

maternal mortality lowers the life expectancy

Explanation:

Lack of basic services refers to the unavailability of essential services (healthcare, clean water, etc) needed by humans to maintain good health.

Maternal mortality: a lack of public health services negatively impacts poor pregnant women in South Africa often leading to avoidable deaths.

Lowers the life expectancy: A lack of basic services leads to underlining health problems that go untreated; thus, reducing the life expectancy of poor people in South Africa.

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
